The lower incidence of bladder cancer among women has led to a lack of information on female radical cystectomy (RC). This study aimed to analyze the characteristics related with female RC in a cohort from multiple academic institutions.
This was a retrospective review of 384 female patients who underwent RC for bladder cancer. Epidemiologic, perioperative variables including urologic referral periodwith consequent pathologic stage distributions were assessed. The changes in surgical techniques over time were illustrated. Also, we evaluated recurrence-free survival (RFS) at 2 and 5 years and overall survival (OS) at 5 years with stage-specific analyses using the Kaplan-Meier method.
The mean follow-up time was 35 months (interquartile rage [IQR], 9 to 55). The average time to urologic referral with initial symptoms was 5.5 (IQR, 1 to 6) months and over 20% of patients visited clinics after 6 months. In subsequent stage distributions according to referral period, T2 or higher stage distributions were abruptly increased after 1 year. Overall 2-year/5-year RFS rates were 0.72/0.57 and 5-year OS was 0.61. Notable surgical descriptions were as follows: 91% of patients underwent open RC; 80% of patients underwent an ileal conduit; and 83% of patients received anterior exenteration. However, the proportions of robotic surgery, orthotopic neobladder and organ sparing cystectomy have increased recen-tly.
We identified the general characteristics and changes in pattern of female RC. Our results also suggest that women are susceptible to delays in referral to an urologist and are at greater risk for worse prognosis.
女性膀胱癌的发病率较低,导致针对女性根治性膀胱切除术(RC)的信息不足。本研究旨在分析来自多个学术机构的队列中与女性 RC 相关的特征。
这是一项对 384 例因膀胱癌接受 RC 的女性患者的回顾性研究。评估了流行病学、围手术期变量,包括泌尿科就诊时间与相应的病理分期分布。说明了随着时间的推移手术技术的变化。此外,我们还使用 Kaplan-Meier 方法评估了特定分期的 2 年和 5 年无复发生存率(RFS)和 5 年总生存率(OS)。
平均随访时间为 35 个月(四分位距 [IQR],9 至 55)。从初始症状到泌尿科就诊的平均时间为 5.5 个月(IQR,1 至 6),超过 20%的患者在 6 个月后就诊。根据就诊时间的后续分期分布,T2 期或更高分期在 1 年后急剧增加。总体而言,2 年/5 年 RFS 率分别为 0.72/0.57,5 年 OS 率为 0.61。值得注意的手术描述如下:91%的患者接受开放性 RC;80%的患者接受回肠导管;83%的患者接受前盆腔脏器切除术。然而,近年来机器人手术、原位新膀胱和器官保留性膀胱切除术的比例有所增加。
我们确定了女性 RC 的一般特征和模式变化。我们的结果还表明,女性容易延迟转至泌尿科就诊,并且预后更差的风险更高。
